Hydrochloric acid is important Chemical Manufacture raw material, is usually used in preparing the chemical products such as metal chloride, aniline and fuel, and is used widely at the industrial departments such as metallurgy, oil, printing and dyeing, leather and food, medicine, plating and scientific research department.
Hydrochloric acid has another name called hydrochloric acid, is monobasic strong acid, obtains by hydrogen chloride gas is water-soluble, has extremely strong volatility, and the hydrogen chloride gas that volatilizes not only has intense stimulus, and very easily is combined with airborne steam and forms hydrochloric acid mist.Therefore, if leaking appears in production, transportation and use procedure in hydrochloric acid, leakage fluid cognition causes serious security incident, healthy and safe and the property loss that the acid mist that the hydrogen chloride gas that volatilizes forms jeopardizes the people, and vegetation destruction very easily, and may cause serious environmental pollution accident.
The disposal of relevant leakage hydrochloric acid, present stage mainly contains neutralisation, accommodates method and water dilution method.Neutralisation mainly is to carry out neutralization reaction with alkaline matters such as quick limes, to eliminate the acid ingredient in the liquid, this method one is to produce easily a large amount of white smoke pollution environment, the 2nd, the incipient stage has the gaseous volatilization of a large amount of penetrating odors, impact is disposed, the 3rd, lack in and the effective ways judged of terminal point, hydrochloric acid leaks the disposal situation therefore to be only suitable for disposing in a small amount.Car accident occurs in the hydrochloric acid transport vehicle in Yiwu, Zhejiang in September, 2012 in the way of travelling, have more than ten barrel of hydrochloric acid to leak, and main employing was exactly quick lime at that time, and not only white cigarette amount is large for the result, the Xiao Bai piece is also formed on the road surface, is difficult to directly remove.
Leak for a large amount of hydrochloric acid and to dispose, generally cut off first source of leaks, accommodate or adopt the measure such as empty by constructing embankment or digging pit, the hydrochloric acid in the groove tank is reclaimed or be transported to disposal site dispose.Remainder then adopts neutralization method or fire water dilution method to dispose, tens of tons of hydrochloric acid leakage accidents that once occured the exactly method of accommodating are disposed, owing to the volatilization hydrochloric acid mist is not carried out establishment or disposal, in and a large amount of white smoke of producing of chemical action spread in the air, the result causes the rescue personnel burnt by acid mist, and in various degree cough, the phenomenon of having a running nose, drop tears occur.
Water dilution method mainly is to be diluted to the permissible scope of environment with the acidity that a large amount of water will leak hydrochloric acid, and the concentrated hydrochloric acid that dilutes in theory 1 cube 37% just needs about 1.2 * 10
7m
3Water, even be diluted to pH=3, also need about 1.2 * 10
4m
3Water, therefore dilution has not only enlarged the leakage pollution area, waste huge water resource, but also can because of the pungent acid mist of volatilization formation, cause personnel health and ambient influnence.
